A month after her fiancé confirmed they were no longer together, Sarah Harding has checked into a rehabilitation clinic.
The 28-year-old singer and actress is being treated in a facility for "depression and alcohol addiction," said a Girls Aloud spokesman.
He added: "There will be no further comment on this matter."
Sarah's fiancé, DJ Tom Crane tweeted in September that the pair had "decided to take a break".
The split came nine months after the party-loving pair announced their engagement.
It's thought the break-up has been hard on Sarah, who has been working on her new British film Run For Your Wife.
Tom is still in Ibiza, where he spent the summer spinning records.
